Definitions

  • the present invention relates to a straddled vehicle including a combined brake system.
  • a combined brake system in which a front wheel brake and a rear wheel brake are operated in a combined manner when a rider of a motorcycle operates a brake pedal is known.
  • Japanese Laid-Open Patent Publication No. 2009-67133 discloses a hydraulic combined brake system.
  • a brake route is set along one main frame extending, above an engine, from a front portion of a vehicle body toward a rear portion thereof.
  • a front elastic hose extends from a master cylinder located to the right of a handle to a central position in a vehicle width direction, and is connected with a connection member located to the front of a head pipe.
  • An intermediate pipe connected with the connection member extends rearward in the vehicle along the main frame.
  • the master cylinder located in the vicinity of the brake pedal is pressed, and the pressing force thereof is distributed for the front wheel brake and the rear wheel brake.
  • the pressing force distributed for the front wheel brake is transmitted toward the front wheel brake via the brake route, and brakes the front wheel.
  • Japanese Laid-Open Patent Publication No. 2014-046798 discloses a vehicle according to the preamble of independent claim 1.
  • the curvature of the combined brake cable is increased.
  • the operability may be deteriorated or the routing workability may be declined.
  • the present inventors made active studies on a structure that decreases the curvature of the combined brake cable.
  • the present inventors paid attention to a large space that was made in a right region of the vehicle and below the main frame, and as a result, conceived that the center of curvature set at a lower position would decrease the curvature of the combined brake cable.
  • a combined brake cable in the case of being routed in the above-described space, is located to be lower and more distanced from the main frame. Therefore, it is difficult to cause the main frame to support the combined brake cable.
  • the present inventors first conceived, by a conventional idea of causing the frame to support the combined brake cable, a structure of causing a downtube to support the combined brake cable.
  • a structure of causing a downtube to support the combined brake cable In a vehicle having a two-downtube frame structure, two downtubes are located respectively in a right region and a left region of the vehicle. Therefore, it is relatively easy for the downtube located in the right region of the vehicle to support the combined brake cable.
  • such one downtube passes a central portion in the vehicle width direction of the vehicle and extends from a front portion to a rear portion, and from a top portion to a bottom portion, of the vehicle. If the downtube passing the central portion of the vehicle is caused to support the combined brake cable, the combined brake cable extending from the downtube at the center of the vehicle to the brake pedal in the right region of the vehicle easily interferes with an engine, which is to have a high temperature.
  • the present invention has an object of improving the operability and the routing workability of a straddled vehicle including a one-downtube frame structure.
  • a straddled vehicle in an embodiment according to the present invention includes a frame including a head pipe; a front wheel and a rear wheel rotatably supported by the frame; a handle supported so as to be rotatable about an axis of the head pipe; an engine supported by the frame; and a combined brake system including a front wheel brake braking the front wheel and a rear wheel brake braking the rear wheel, the combined brake system operating the front wheel brake and the rear wheel brake in a combined manner.
  • the frame includes a main frame extending rearward from the head pipe, the main frame supporting the engine such that the engine is below the main frame; and one downtube extending downward and rearward from the head pipe so as to be at least partially located to the front of the engine.
  • the combined brake system includes a front wheel brake actuator provided on the handle, the front wheel brake actuator actuating the front wheel brake in response to an operation made by a rider; a rear wheel brake actuator provided to the rear of, and below, the front wheel brake actuator, the rear wheel brake actuator actuating the rear wheel brake in response to an operation made by the rider; and a combined brake cable connected with the front wheel brake actuator and with the rear wheel brake actuator, the combined brake cable transmitting an operational force applied to the rear wheel brake actuator to the front wheel brake actuator.
  • the front wheel brake actuator is located in a first area, which is one of two areas separated from each other as being to the right of, and to the left of, a vehicle center line as seen in a vehicle plan view.
  • the combined brake cable is routed in the first area, and at least partially overlaps the engine as seen in a vehicle side view.

  • the combined brake cable may at least partially extend downward and rearward from a position to the front of the engine.
  • water may enter the inside of the combined brake cable.
  • the combined brake cable extends downward and rearward from a front portion of the vehicle. If there is a portion of the combined brake cable in which a rear portion is located at a higher position than that of a front portion (if there is a portion hanging in a U-shape protruding downward), water is stored in such a portion and it is made difficult to discharge the water from the rear portion of the combined brake cable.
